Incorrect selection of kernel headers: expected 4.6.x, got 4.13.x #34

Trying to build a fresh checkout of freedom-u-sdk using make qemu.

$ git branch -v
* master 783c89a linux_defconfig: support software restart

QEMU builds okay, but then I get an error with buildroot. I've done git submodule update --init --recursive and everything is up-to-date.

$ make qemu

I spent a lot of time mucking with buildroot in early December and coudn't get it to work due to similar sorts of errors with gcc and linux header version dependencies. I tried fixing it but I gave up hacking on buildroot and went ahead and made a tiny busybox+dropbear linux root image builder. Caveat: it requires sudo as it loop mounts an ext4 filesystem

There is obviously some buildroot patches I must be missing or I'm on the wrong branch. When I run it a third time, the build log is shorter, but I get the same error.

It's possibly my linux toolchain version. My linux toolchain is top-of-tree default master branch of riscv-gnu-toolchain as of 01-Feb-2018

Try unset RISCV before running make in a clean checkout of freedom-u-sdk. It will use it's own known-to-work toolchain then.

michaeljclark commented 6 years ago

Oh that's good to know. I'll give it a try.

We probably should have master (default branch) in riscv-gnu-toolchain pointing at a newer toolchain. I'll try and figure out which branch freedom-u-sdk is using...

michaeljclark commented 6 years ago

We have quite a few repos that build private copies of the toolchain (freedom, freedom-u-sdk, freedom-e-sdk, riscv-tools (if built separately) and riscv-gnu-toolchain (if built separately). Hopefully, we'll be able to fix some of these issues by using packaged dependencies instead of submodules. At some point...

@palmer-dabbelt @jim-wilson what branch of riscv-gnu-toolchain does freedom-u-sdk depend on? linux-headers-4.15-rc3? master in riscv-gnu-toolchain seems to be a little behind.

michaeljclark commented 6 years ago

Appears to be the issue. The build is getting a lot further... it is still building...

I'll leave the issue open as its likely many folk will have RISCV set.

We should probably add a test for the headers if an external toolchain is being used.

We could perhaps add it to the README.md when we give it a README.md. I can make a PR...

AndreRH commented 6 years ago

Hacky but works: in buildroot/support/scripts/check-kernel-headers.sh change the line return 1; -> return 0;

terpstra commented 6 years ago

the documentation now includes a comment about this gotcha
